In my first private server, in the first day, I wrote my own guide by step to step, while I trained the summoning. That guide is fully created for 317 servers, depends on the xp rates it's useless for higher revision servers. Unfortunately during 4 years after I created it, one information lost, how many charms you need. I can suggest start the Slayer skill, and use 30 gold, blue, green charm, and 3000 crimson. After you reach a level where you can made some pouch which needs crimson charm, the best if you use that pouch till you reach the other pouches which needs crimson charms. In the end, the Swamp Titans give the highest xp what you can earn.
